The early years of Real Housewives of Beverly Hills revolved around the tension and animosity between Kyle Richards and her sister Kim Richards. Kyle outed Kim as an alcoholic in the back of a limo during the season 1 finale. They also spent that whole first season reminding people that they’re Paris Hilton’s aunts, a fun fact that has lost its luster in recent years. Kyle sided with Lisa Rinna when she threw a glass at Kim during the cast trip in Amsterdam.
Then, Kim and Kathy Hilton took issue with Kyle for producing a failed scripted series based on their family. Kyle has had many ups and downs with both Kim and Kathy over the years. Still, we have seen some small cameo appearances from Kathy throughout the years. Now, there are rumblings that Kathy will join the cast for Season 11.
